ID CVE-2016-5011
Summary The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero offset.

    description From Red Hat Security Advisory 2016:2605 : An update for util-linux is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The util-linux packages contain a large variety of low-level system utilities that are necessary for a Linux system to function. Among others, these include the fdisk configuration tool and the login program. Security Fix(es) : * It was found that util-linux's libblkid library did not properly handle Extended Boot Record (EBR) partitions when reading MS-DOS partition tables. An attacker with physical USB access to a protected machine could insert a storage device with a specially crafted partition table that could, for example, trigger an infinite loop in systemd-udevd, resulting in a denial of service on that machine. (CVE-2016-5011) Red Hat would like to thank Michael Gruhn for reporting this issue. Upstream acknowledges Christian Moch as the original reporter. Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.
